Browser-based station
Web Serial connects Chrome or Edge straight to the CLM8 — nothing to install or maintain on the workstation.
CVWSCommercial Vehicle Weighing System
Vehicle weighing from the scale to the cloud on web and mobile.
CVWS connects directly to Laumas CLM8 load-cell transmitters over Modbus RTU, streaming live gross and net weight to a web dashboard or iOS/Android app. Every weighing session creates a timestamped, organization-scoped record — accessible across sites, roles, and devices.

Web Dashboard
Operate from Chrome or Edge — no software to install.
CVWS runs entirely in the browser. Connect a CLM8 over the Web Serial API, watch live weight stream in, and capture a complete weighing session without a proprietary terminal or a desktop install.
- Live gross/net + per-channel readoutLive gross and net weight plus the per-channel mV readout from all eight load cells, streamed over the Web Serial API.
- One-click connectConnect through the Chrome device picker — the CLM8 9600 8N1 defaults are preset, so it is one click from the dashboard.
- Two-step weigh workflowCompany + vehicle ID, then empty, then loaded — ending in a printable receipt. The flow mirrors how a yard actually weighs.
- Searchable weight historySearch the full weight history — all eight mV channels captured per session — by vehicle, date, or site.
- Per-organization data isolationEach organization’s sessions, vehicles, and history are isolated — a shared platform that never leaks across tenants.
- Role-based accessServer-enforced, per-organization permissions decide who can weigh, who can view history, and who can administer the org.
iOS & Android Apps
Weigh with a Mobile App.
The CVWS mobile apps put the same weighing workflow on the device already in the operator’s pocket. Both apps are in App Store and Google Play review; download links go live when approved.
- BLE connection — no laptopConnect to the CLM8 over Bluetooth Low Energy straight from the phone — no laptop, no cables, no dongle.
- Live weight on the deviceThe live weight display reads clearly on the device, sized for the cab or the curb.
- Same workflow, mobile-nativeThe same two-step weigh workflow as the dashboard, rebuilt mobile-native for touch.
- Synced to the cloudField captures sync to the same cloud platform as the dashboard, so the office sees them immediately.
- Enterprise SSO sign-inSign in with enterprise single sign-on (SSO) — email, Google, Apple, or Microsoft — the same identity used on the web.

What you get
One platform across the browser, the yard, and the office.
A browser dashboard, native iOS and Android apps, and a secure multi-tenant cloud platform — all reading the same Laumas CLM8 hardware and writing to the same organization-scoped records.
Native mobile apps
iOS and Android apps connect over BLE and run the same two-step weigh workflow, mobile-native.
Live gross/net + 8-channel mV
Live gross and net weight with the per-channel millivolt readout from every one of the eight load cells.
Timestamped session records
Every weighing session is a timestamped record with the full 8-channel mV snapshot, searchable by vehicle, date, or site.
Multi-tenant by design
Per-organization data, roles, and membership keep each tenant isolated on shared infrastructure.
Printable receipts
The two-step workflow ends in a printable receipt — empty, loaded, and net, ready to hand off or file.
Hardware-faithful
Built on the Laumas CLM8 register map.
CVWS speaks the CLM8’s native Modbus RTU protocol directly — reading the documented register map with CRC16 validation, polling at roughly 1 Hz, and capturing all eight load-cell channels every session.

Why CVWS
Designed for zero-client vehicle weighing.
Audit-ready records
An append-only membership audit log plus a full 8-channel mV snapshot captured with every weighing — the trail a commercial weighing operation needs.
Multi-tenant by design
Per-organization data, roles, and membership; the first login auto-provisions an org admin. Sign-in uses enterprise single sign-on (SSO), and per-organization permissions control who can weigh, view history, and administer.
Hardware-faithful protocol
Reads the CLM8 register map with CRC16 validation, polls at roughly 1 Hz, and captures all eight load-cell channels — the recorded weight is the weight on the scale.
Questions & answers
Frequently asked questions
What is CVWS?
CVWS (Commercial Vehicle Weighing System) is software that connects directly to Laumas CLM8 load-cell transmitters and streams live gross and net weight to a browser dashboard or native iOS and Android apps. Every weighing session creates a timestamped, organization-scoped record with the full eight-channel millivolt snapshot, accessible across sites, roles, and devices.
What do I need to run it — is there software to install?
No desktop install on the web side. The CVWS dashboard runs entirely in Chrome or Edge and connects to a CLM8 over the Web Serial API. On phones, the iOS and Android apps connect to the CLM8 over Bluetooth Low Energy — no laptop, cables, or dongle. It reads the Laumas CLM8 (8 load cells) over its native Modbus RTU protocol at 9600 8N1.
Are CVWS weight readings certified for legal-for-trade use?
No. CVWS weight readings are not certified for legal-for-trade or regulatory use. CVWS reads the CLM8 register map directly with CRC16 validation and captures all eight load-cell channels every session, so the recorded weight is the weight on the scale — but it carries no NIST Handbook 44 or legal-for-trade certification.
Is my data isolated from other companies?
Yes. CVWS is multi-tenant by design: each organization’s weighing sessions, vehicles, and history are isolated and never leak across tenants. Sign-in uses enterprise single sign-on (SSO) — email, Google, Apple, or Microsoft — and server-enforced, per-organization permissions decide who can weigh, who can view history, and who can administer the organization.
Does it keep an audit trail of weighing activity?
Every weighing session is a timestamped record that captures the full eight-channel millivolt snapshot and is searchable by vehicle, date, or site, alongside an append-only membership audit log. This is the kind of record a commercial weighing operation needs — it is a capability, not a regulatory certification.
